Our verse is something of a summation of everything he has previously written. The Greek word oun, translated “therefore,” is a way of saying, “In light of everything I’ve said to this point, if you know to do good and you don’t do it, then to you … it is sin.” And we don’t want to be guilty of sin because apostle Paul warned that the “wages of sin is death” (Ro 6:23). Yet the Bible teaches that sin is both doing the wrong thing, and also refusing to do the right thing we knew we should have done.
